Continuous joint measurement and entanglement of qubits in remote cavities

2015 · Physical Review A

We present a first-principles theoretical analysis of the entanglement of two superconducting qubits in spatially separated microwave cavities by a sequential (cascaded) probe of the two cavities with a coherent mode, that provides a full …

Dispersive Qubit Readout with Intrinsic Resonator Reset

2024 · JuSER (Forschungszentrum Jülich)

A key challenge in quantum computing is speeding up measurement and initialization. Here, we experimentally demonstrate a dispersive measurement method for superconducting qubits that simultaneously measures the qubit and returns the readout resonator to its …

Universal pulses for superconducting qudit ladder gates

2024 · JuSER (Forschungszentrum Jülich)

Qudits, generalizations of qubits to multi-level quantum systems, offer enhanced computational efficiency by encoding more information per lattice cell, avoiding costly swap operations and providing even exponential speedup in some cases. Utilizing the $d$-level manifold, …
